A lot runs between two parallel streets. The length of the lot on one of the streets is 160-ft. The length of the lot on the oth
Daniel [21]

Answer:

Step-by-step explanation:Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

Hope this helps :-)Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

How do you do this?<br> Please help, I’ve been staring at this for like 10 min :)
damaskus [11]

Answer & Step-by-step explanation:

The formula is given in the middle. You are supposed to insert the value of x into this formula to find the value of y (like in the first given example):

x=-2\\y=2(-2)+5\\y=-4+5\\y=1

------

x=-1\\y=2(-1)+5\\y=-2+5\\y=3

------

x=0\\y=2(0)+5\\y=0+5\\y=5

------

x=1\\y=2(1)+5\\y=2+5\\y=7

------

x=2\\y=2(2)+5\\y=4+5\\y=9

:Done
